There is a modbus slave application example on this website. Note that modbus slave is not "officially" supported until version 6 - the example uses serialLib and works on older versions of xA

I would recommend to use Modbus Slave-Slave converter between the systems if other system can not be changed to slave. AC500 controller should be easy to program to work as Modbus Slave-Slave converter.
